 |
|
Hi!
My problem is very simple. I have a hitachi NESO external drive that I can't connect on my PC. I have updated my gentoo-souces to "gentoo-sources-2.6.30-r6" but the problem is still here.
Dmesg :
Here is the looping procedure:
The kernel founds the external drive :
| Code: |
[ 360.447036] usb 1-1: new high speed USB device using ehci_hcd and address 8
[ 360.529245] ehci_hcd 0000:00:02.2: port 1 high speed
[ 360.529254] ehci_hcd 0000:00:02.2: GetStatus port 1 status 001005 POWER sig=se0 PE CONNECT
|
It reads its caractéristics :
| Code: |
[ 360.595270] usb 1-1: default language 0x0409
[ 360.612282] usb 1-1: New USB device found, idVendor=1bcf, idProduct=0c31
[ 360.612288] usb 1-1: New USB device strings: Mfr=2, Product=3, SerialNumber=1
[ 360.612292] usb 1-1: Product: 320GB
[ 360.612295] usb 1-1: Manufacturer: NESO
[ 360.612298] usb 1-1: SerialNumber: 00021dc3
|
It starts SCSI emulation :
| Code: |
[ 360.612402] usb 1-1: uevent
[ 360.612428] usb 1-1: usb_probe_device
[ 360.612433] usb 1-1: configuration #1 chosen from 1 choice
[ 360.613508] usb 1-1: adding 1-1:1.0 (config #1, interface 0)
[ 360.614158] usb 1-1:1.0: uevent
[ 360.614193] usb-storage 1-1:1.0: usb_probe_interface
[ 360.614202] usb-storage 1-1:1.0: usb_probe_interface - got id
[ 360.628091] scsi238 : SCSI emulation for USB Mass Storage devices
[ 360.643732] drivers/usb/core/inode.c: creating file '008'
[ 360.643795] usb-storage: device found at 8
|
But next, an error occur:
| Code: |
[ 360.643798] usb-storage: waiting for device to settle before scanning
[ 360.677308] hub 1-0:1.0: state 7 ports 6 chg 0000 evt 0002
[ 360.677324] ehci_hcd 0000:00:02.2: GetStatus port 1 status 001c09 POWER sig=? PEC CONNECT
[ 360.677331] hub 1-0:1.0: port 1 enable change, status 00000501
[ 360.677338] hub 1-0:1.0: port 1 disabled by hub (EMI?), re-enabling...
[ 360.677343] hub 1-0:1.0: port 1, status 0501, change 0002, 480 Mb/s
|
And the kernel closes the USB :
| Code: |
[ 360.677348] usb 1-1: USB disconnect, address 8
[ 360.677351] usb 1-1: unregistering device
[ 360.677355] usb 1-1: usb_disable_device nuking all URBs
[ 360.677362] usb 1-1: unregistering interface 1-1:1.0
[ 360.677707] usb 1-1:1.0: uevent
[ 360.677859] usb 1-1: uevent
[ 360.781036] hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x501
|
This procédure is looping and I hear an looping song on the drive.
Any idees? What can I do? |
